The blocking plate 4519 abuts against the outlet of the mounting groove 11. The valve seat 41 is limited in axial movement by the limiting step 4513, the limiting protrusion 4512 and the card.

[0043] When the blocking component 4518 is a screw, the screw can be directly locked to the valve bottom wall 411, and the nut of the screw can abut the outlet of the mounting groove 11. When the blocking component 4518 is a hose connector, the hose connector is connected to the water inlet pipe 5, and the hose connector may include a blocking block facing the outlet of the mounting groove 11. When the hose connector is connected to the water inlet channel 414, the blocking block abuts the outlet of the mounting groove 11.

The top block 4514 also includes a through groove 4515 that passes through the extending direction of the connecting groove 12, and the drawing tube passes through the through groove 4515. The top block 4514 abuts against the inner wall of the housing 1 and prevents the valve seat 41 from moving further.
